This unit was manufactured in 1985.\u003cbr\u003e\u003cbr\u003eIt features the asymmetrical overdrive circuit inherited from the OD-1, along with a new tone control that allows for high-frequency boost or cut. Thanks to subtle circuit modifications, it offers a slightly higher gain and a more solid tone compared to the OD-1.It produces a sweet, mild distortion without killing the subtle nuances of your picking. The op-amp used is a JRC4558DD (matte finish); other variants include the NEC C4558C’ used in the very early models and the JRC4558D used around 1982. The SD-1 was manufactured domestically until mid-1989, after which production was moved to Taiwan.\u003c\/p\u003e \u003cp\u003e PCB: ET5212-510B\u003cbr\u003eOP-IC: JRC4558DD (#4287)\u003cbr\u003eACA adapter compatible\u003c\/p\u003e \u003cp\u003e Year: 1985\u003c\/p\u003e \u003cp\u003e Accessories: None\u003c\/p\u003e \u003cp\u003e Contact: Kikushima\u003c\/p\u003e \u003cp\u003e *The warranty period is one month from the date of purchase.\u003c\/p\u003e \u003cp\u003e [We are currently offering enhanced trade-in values!!] We offer high prices for all items, including current popular models, high-end boutique brands, and rare or niche models!
